Accordingly, tl

1, there is shown a depending support in the form of a hollowing, post adapted to be carried by an arm 11 in turn supported for vertically adjustable movement and containing an electric power cable 12. Secured to the flange 13 forming the lower part of the post 10 and depending therefrom is a central support lshthe upper portion of which is a spoolshaped cylindrical member 15 and the lower portion of'which is a frusto-conical shell 16. The spool-shaped member 15 includes an upper flange 17 to which is secured the upper inner edge of a mechanism containing dome 18 fastened in place by means of screws 19. The lower flange 20 of the member 15 provides a seat for an elevator stop plate 21, the outer circular edge 22 of which is adapted to limit the upward movement of elevators hereinafter described and as shown in dotted lines in Fig. 1. Extending across the lower open end of the cone shell 16 is a spider 24and the bottom of the dome 18 is closed by means of a bottom cover plate 25 secured centrally to the spider 2 1.

Secured to the underside of the cone 16 by means of the screws 26 and which screws also secure the spider in place, is a box 27 including an outlining peripheral wall 28 which forms a mounting for a series of double plug sockets 29 extending therethrough. The lower edge of the wall 28 is outbent as shown at 30 and is secured to the cover plate by means of the screws 26. The portion of the cover plate 25 eXt-eriorly of the box 21' constitutes or is provided with means for guiding the cables 31 leading to electricheaters 32. This outer portion of the bottom cover plate is referred to hereinafter as a guide mountmg plate 33.

The guide mounting plate is provided with a plurality of passageways 34 (see Fig. 2), one for each of the sockets 29 and the center of each passageway is disposed approximately in axial alignment with the associated socket. Each passageway 3 1 is provided with a pair of diametrically disposed slots 35 and see Fig. 2) disposed on opposite sides of the axis of its associated socket and each provided with a guiding ring 37 (see Fig. 5) inserted in place through the associated passageway and moved edgewise to the end of the slot where it is held in position by a U- shaped spring clip 38 fitted between an end flange 39 and the adjacent face of the plate. A flange 10 defining the opposite end of the ring bears on the opposite or underside of the plate 33 as particularly shown in Fig. 5. From this construction, it is apparent that one or both of the guiding rings can be readily demounted simply by withdrawing its holding clip and sliding the same out through the passageway.

In manufacturing the replaceable unit including the electric leads, the guiding rings will be mounted one on each of the cables 31 and\ positioned between the heater 32 at one end bf the cable and the screw plug e1 the other end of the cable and which plug when screwed into position constitutes the removable element of the socket 29. In the showing illustrated two cables and therefore two electric heaters are connected to each plug 4-1 as shown in the upper part of Fig. 2. 'Differently expressed, a single socket supplies two adjacent electric heaters but it is obviously within the scope of the disclosure to supply more than two heaters from single socket. In this case, it will be necessary to provide additional slots radiating from the passageway so as to gun ie the cables so as to fall free of each other. The several sockets are supplied from the power lead 12 by branch conductors 12 leading circularly about the inside of the box 27 to the several sockets in the completed circle of sockets.

It is desirable in devices of the class described to elevate the heaters when not in use into an out-of-the-way position and for this purpose there is disclosed cable elevators which are pivoted at their inner ends to the central cone 16 and having a length so that when raised they take up the slack in the cables. These elevators have each rot-stably mounted at its outer end a pulley -.3 about which are turned cable 81, one cable to each elevator as particularly illustrated in 2. The elevators are each controlled by an upwardly extending spring as acting on the elevators when released from the weighof the heaters to move into the elevated pos n shown in dotted lines in Fig. 1 and in position to raise its associated heater from its operative position adjacent the persons head into the raised position as shown to the left of Fig. 1. The elevators are limited in their upward movement by abutting against the outer ed e 22 of the stop plate and Ye limited in their depressed position by eng .gement with the mounting plate 33.

It is a feature of this disclosure that the elevators be designed so as to be quic tly removed. For this purpose, the inner pivotally mounted ends of the elevators are prov d in the form shown in Figs. 3 and with an upwardly facing slot 15 designed to receive and underlap a pivot pin 46 and which preferably is a wire as shown in Fig. 2 threaded through fingers 47 forming extensions from the lower part of the cone 16. Similarly the upper ends of the springs 4.4. engage a wire 4-8 threaded through fingers e9 constituting projections from the upper side of the cone 14;. From this construction it is appreciated that the springs may be readily demounted from the wire 48 as by unhoohing the same and the elevators may be removed from their pivotal connections simply by with drawing the lower ends of the elevators from the wire when the elevator is in the upwardly disposed position shown in dotted lines in Fig. 1.

l vith Ell the elevator separated from the cone, it may be withdrawn through the passageway 34, which is of sufficient cross sectional area to permit the removal of the elevator as a whole. It is also understood that the plug 41 may be similarly withdrawn through the passageway 34.- in den'iounting the cable 31 and plug as a whole from its associated socket.

The specific form of elevators selected herein for illustration in Figs. 3 and 4 includes a readily deinountable form of pulley and means for securing the cable in engagement with the pulley so that it will not accidenta 3 siio ot't' the pulley. In the showing in Fig. 1 will be noted that the elevator formed of a pair of parallel side plates 50 connected by a pair of spacing rivets 51. The plates at one end are offset from each other to provide a broad bearing 52 containing the slots and the opposite end mounted so as to be sprung apart. This opposite end is provided with. oppositely disposed integral aligned pivot studs 53 which coact to provide a pivotal bearing for the pulley 463. The pulley containing ends of the plates are held in position to mount the pulley ri'itatably by means of a clamp 54 straddling the ends of the plat-es, pivoted to one of the plates on pin 55 and provided with a finger piece 56 by means of which the clamp is readily moved to and from its clamping position. It is understood from this construction that releasing the clamp permits the cable to be threaded between the plates and the pulley so that when the clamp is in operative position there is no possibility of the cable escaping from the pulley.

In the a modified form of the elevator mounting shown in Fig. 5, a peripheral cam shaped hub 57 is secured to the pivotally mounted end of the elevator and a flexible extension 58 from the spring 44: underlaps and is trained about the periphery of the cam and secured thereto at 59. The cam is laid out so to compensate in lever arm length for the varying resistance of the spring as the elevators are shifted incidental to the raising or lowering of the suspended heater. With a properly designed cam and spring the elevators will automatically take up the slack from any position at which the heaters may be set, and there will be no variations in resistance to the shifting of the heaters irrespective as to their position in the space beneath the chandelier.

Referring to the modified form of the central support of the elevators shown inFigs. 7 and S, the central support 14 of the preceding figures is replaced by adepending post 60, the upper end of which 1s threaded into the support 10. Threaded on to the upper portion of the post 60 is a collar 61 between the top ol which and a nut 62 is contained the top of the dome 18. The lower end of the collar 61 is provided with an outstanding flange 63, the periphery of which is outlined by steps 64, one for each of the elevators pivotally connected to the post 60 therebelow. Threaded into each of the step faces 64 is a stop 65 adapted to constitute an adjust flO abutment for receiving the elevators they are swung into their upstanding positions as shown in dotted lines in Fig. 7.

To the bottom of the post 60 is screwed an elevating supporting collar (36 provided with an outstanding flange 67. The periphery of the flange is stepped to correspond to the steps 64 in number on the upper collar. Each of the steps 68 is provided with a rectangular recess 69 for receiving the inner end 70 of the elevators 23, it being understood of course that there is one recess for each elevator. In stead of having the elevators extend radially from the center of the support as indicated in the showing in 2, the elevators in the modified form have their inner ends slightly overlapping each other considered circumferentially in one direct-ion so as to economize in space and reduce the all-over diameter of the dome as a whole and at the same time provide the maximum possible length to the elevators. For this purpose the recesses 69 extend as far as is practically possible into the flange 67 and are disposed substantially parallel to a tangent to the outer periphery of the collar portion 66. The inner ends of the elevators are pivotally mounted on pins 71 driven into the flanges 67 to extend across the rcce s 69. The stepped construction oi the periphery of the flange 67provides access along the exposed faces 72 to permit the insertion and withdrawing at will of the pivoting pin. Differently defined, the elevators extend in direction each substantially tangent to a centrally positioned circle such as the outer periphery of the coller 66.

In operation, it is understood that the chandelier functions as is at present known in similar devices now on the market. Nor mally, the heaters are elevated up close to the underside of the cover plate when not in use and the operator simply reaches up and draws the heaters into position one after the other as they are needed, leaving elevated any heaters which might not be required for any particular treatment. lVith certain, or all of the heaters in operative position, the operator turns on the current to either the entire set or preferably to those heaters which are in use and which control is attained by switches forming no part of the present disclosure.

As each heater is lowered into operative position it will draw on its associated cable and the cable will react through the pulley on its associated elevator to depress the same from the dotted line or towards the full line position shown in Fig. 1. Even with the form of elevators shown in F igs. 14, there will be a tendency for the heaters to remain wherever they may happen to be set. In the cam form o1"- spring actuated elevating means shown in Fig. 5, the lifting tendency of the spring acts simply to counterbalance the weight suspended from the pulley and this weight leverage will be constant and substantially independent of the angle of the elevator relative to its limiting positions.

Should any one heater, its cable or asso-' ciated elevator, become damaged, inoperative or worn or for any other reason requiring replacement, the dome may be readily removed or the cover plate lowered and the elevator disconnected as previously suggested. parts removed can be dropped out through the passageways in the bottom of the device and the remaining part restored for operative use. The cable can be disconnected from its elevator simply by releasing the clamp and the damaged part returned to the factory for repair, after which the repaired part or a substitute part may be replaced as is obvious.

It is possible when using the form or elevator mounting shown in Figs. 7 and 8 to increase the length of the elevators over the length shown in the form of mounting disclosed in Fig. 1 without enlarging the overall dimension of the device. The rigid collar for pivotally supporting the elevators can be made sufficiently massive to withstand strain incidental to use and at the same time the staggering arrangement of the elevators in their lapped positions provides the necessary space to accommodate the longer elevators.

By means or a device such as is herein disclosed, it is possible forthe unsk lled operator to remove a damaged part without mati-n'ially affecting the usefulness of the device as a whole and where substitute parts are carried in stock any damaged part may be quickly replaced and the entire device restored for operation.
